Question 1

How many vials are in a kit?

Accepted Answer

Ten. A kit is 10 vials of the same product and strength.

Question 2

What is the minimum order?

Accepted Answer

One kit per product and strength. Different products and strengths can go in one order, each from one kit.

Question 3

Which copper products are stocked?

Accepted Answer

The copper peptides GHK-Cu and AHK-Cu, and three copper blends: GLOW (42 and 70 mg), KLOW (80 mg) and a 50 mg vial of GHK-Cu, TB-500 and BPC-157; the strengths are listed on each product page.

Question 4

What is a copper blend?

Accepted Answer

One vial holding GHK-Cu together with other peptides, lyophilized as a single powder. In GLOW, KLOW and the 50 mg blend, GHK-Cu is the only peptide that carries copper; each product page lists the milligrams of every peptide per vial.

Question 5

Can I order peptides that are not copper peptides?

Accepted Answer

Yes. The full range page lists every product in our catalogue with its vial strengths; tap a strength to ask for a quote. They are sold the same way: 10 vials per kit, from one kit.

Question 6

In what form are the peptides supplied?

Accepted Answer

As a lyophilized (freeze-dried) powder sealed in glass vials. GHK-Cu powder is blue because of the bound copper, and the copper blends take their colour from their GHK-Cu.

Question 7

Is GHK-Cu available as a nasal spray?

Accepted Answer

Yes — GHK-Cu 100 mg is filled in 10 mL or 20 mL nasal spray bottles too, with a minimum of 10 bottles per size. They are dispatched within the United States from stock we keep there; sales send the written quote.

Question 8

What are the products sold for?

Accepted Answer

Research use. Every product on this site is sold for research use only.

Question 9

How do you quote?

Accepted Answer

In writing, by the kit. Prices are tiered by the number of kits of each product and strength, and the quote states the unit price, shipping and lead time.

Question 10

How quickly do you reply?

Accepted Answer

Within 24 hours, with a written quote or with the questions sales need answered first.

Question 11

What should I put in my inquiry?

Accepted Answer

The product and strength, the number of kits of each, the destination country, when you need the order, the documents you need, and whether you want your own labels.

Question 12

How do I pay?

Accepted Answer

Payment is not taken on this website. After you accept the written quote, sales arrange payment with you by chat or email.

Question 13

Where do orders ship from?

Accepted Answer

From China, by international express; the GHK-Cu nasal spray ships from our US stock instead. The transit time to your country is stated in the quote.

Question 14

Can kits carry our own labels?

Accepted Answer

Ask sales. Custom labels are quoted with the order, after the label design is agreed.

Question 15

What does the batch COA report?

Accepted Answer

HPLC purity, MS identity, bacterial endotoxin and fill, for the batch whose number it carries. Each batch of a stocked product has its own COA.

Question 16

Can I see the COA before I order?

Accepted Answer

Yes. Ask for the COA of the batch you would receive; sales send it with the quote. Low-resolution first pages of batch COAs, one per strength, are on the batch-data page and the product pages.

Question 17

Is copper content on every COA?

Accepted Answer

Copper content, the Cu²⁺ : peptide ratio and UV-Vis are available on request and agreed before the quote. Every COA carries HPLC purity, MS identity, endotoxin and fill.

Question 18

Do you have third-party test reports?

Accepted Answer

Yes, for GHK-Cu 50 mg, from a third-party laboratory in Tianjin, China. A low-resolution first page is on the home page, the batch-data page and the GHK-Cu product page; the full report is sent by sales on request.

Question 19

What if my own lab test shows the product is out of specification?

Accepted Answer

Test it yourself. If it fails, you get a full refund. Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.

Question 20

Why is GHK-Cu blue?

Accepted Answer

Its copper(II) ion absorbs light in a broad band near 606 nm, in the orange-red part of the spectrum, so the material looks blue. A white powder sold as GHK-Cu has no bound copper.

Question 21

Why do suppliers list different molecular weights for GHK-Cu?

Accepted Answer

They describe different forms: 401.91 g/mol is the neutral 1:1 complex, 742.3 g/mol the 2:1 form with two GHK per copper, and 340.38 g/mol copper-free GHK. Ask which form a document describes.

Question 22

Which CAS number belongs to GHK-Cu?

Accepted Answer

89030-95-5, the copper complex. 49557-75-7 is copper-free GHK, so a GHK-Cu offer quoting it names the wrong material.

Question 23

Is GHK the same as GHK-Cu?

Accepted Answer

No. GHK is the tripeptide without copper; GHK-Cu is its copper(II) complex, with a different CAS number, molecular weight and colour.
